Franklin County Heating & Cooling Services

The Franklin County climate record

One record, one county: the normals at ST LOUIS LAMBERT INTL AP, MO US — 4,433 heating degree days, 1,713 cooling degree days, 41.7 inches of precipitation, an average temperature of 57.4 degrees — applied to Franklin County's own 923 square miles and its 20 ZIP codes. The figures are the St. Louis metro's; the ground they are applied to, lying southwest of the St. Louis metro's centre, is this county's alone, and this section reads the two together.

Heating writes this county's HVAC calendar. With 4,433 heating degree days against 1,713 cooling degree days in the normals recorded at ST LOUIS LAMBERT INTL AP, MO US, the systems across Franklin County earn their keep in the cold half of the year: furnaces and heat pumps cycling through 84.9 nights at or below freezing, when a breakdown stops being a comfort problem and becomes a household one. The pressure shows up as midwinter failures on the oldest equipment first, and a maintenance calendar that has to be kept in autumn — because by the time the cold arrives, the county's systems are already on stage.

The county's neighbours frame it as well: St. Clair County, St. Louis City, St. Louis County are among the 14 counties on its neighbour list, and together they form the working ground around Franklin County's own 923 square miles. A system near a shared border lives in both counties' weather at once, whichever page describes its home — the pages divide the map so the record can be read county by county, and the links between them keep the whole in view.

A ZIP code in Franklin County is a small climate-and-housing district of its own. The county's 20 codes — 63013, 63014, 63015, 63037 among them — all read the same normals from ST LOUIS LAMBERT INTL AP, MO US, yet the systems inside them were installed in different decades, serve different house sizes, and fail in different orders. That is why this page prints the whole list rather than a summary: the codes are the finest division of the county the data supports, and they are the division the work itself follows.

Position first: Franklin County lies southwest of the St. Louis metro's centre, roughly 46 miles from the metro's centre as the map measures it, with St. Clair County, St. Louis City, St. Louis County among the counties around it. Neighbourhood at county scale matters to heating and cooling because systems do not respect the border — the same subdivisions' building decades continue across it, the same cold snaps and heat waves examine both sides in the same night — while each county's page, this one included, keeps the local figures distinct.

The precipitation figure earns its place in Franklin County's record: 41.7 inches a year at ST LOUIS LAMBERT INTL AP, MO US, falling through both the cooling months and the heating ones. Rain loads condensate systems in summer, tests outdoor units and venting in winter, and keeps the ground around the county's 20 ZIP codes cycling between wet and dry in a way that shows up in crawl spaces and condensate lines. Set beside 47.1 hot days and 84.9 freezing nights, it completes the picture of what the county's equipment actually lives in.

Communities and housing in Franklin County

The codes carry the community story in Franklin County: 20 of them, from 63013 through to 63090, at 46.1 square miles per code across the county's 923 square miles. Nobody here describes a call by its town, because the record gives the county no towns to describe it by; they describe it by its code and its road. The housing behind those codes was still built decade by decade, and the systems still age decade by decade — the county simply files the diary by ZIP instead of by place.

Look at the second era as well as the first and Franklin County's stock comes into focus. After the dominant band — homes built before 1960, 33.8% of the metro's total — the next share was built between 1960 and 1979, at 25.0%. Between them those two bands account for most of the systems a technician will open in this county, and they are different machines in different houses: the earlier band's equipment fitted into older envelopes, the later band's into the standards of its own decade. The county's diary is the two bands, interleaved street by street.

The county is worth a page of its own because its facts do not reduce to its metro's. The St. Louis metro supplies the climate station and the housing profile, but Franklin County supplies everything at ground level: 923 square miles, its own communities and codes, its own neighbours — St. Clair County, St. Louis City, St. Louis County among the 14 on its list — and its own position, southwest of the St. Louis metro's centre. The metro page and this page link to each other because neither half of that picture stands well without the other.

Our role in Franklin County, stated plainly

TempReach USA is not an HVAC company. We employ no heating or cooling technicians, we run no service trucks, and we do not carry out HVAC work of any kind. This website and its call center exist for one purpose: to connect homeowners with independent local heating and cooling professionals who serve their area. When you call the number on this site, your call is routed to such a professional. From that point, everything about the job belongs to that professional and to you: the assessment, the work itself, the scheduling, what you are charged, and the terms of any agreement you reach. The professional who takes your job is solely responsible for it. The technician who arrives at your home runs their own business; they are not an employee, agent or subcontractor of TempReach USA. Our part is the information on these pages — assembled from Census Bureau housing data and NOAA climate records for each metro — and the routing of your call. We state this plainly on purpose: you should know exactly who you are hiring before anyone picks up a wrench or a gauge.
